Having a weird issue. When I spin my rear tire my drive chain at some points is loose and has 3/4 inch slack another half turn its super tight with almost no slack.
Your first idea was also mine. The sprocket is not centered on my hub , right ? Wrong.
I measured with a tape measure , did the string method then finally I made a jig to hold a screw driver to actually see if it was not centered while the wheel was spinning. Its practically dead nuts. I marked my sprocket with a marker 12 & 6 and 9 & 3 o'clock Im not off more then a 1/16 an inch any way.
My tire and sprocket are both true the other way too , left to right.
On the compression stroke do these engines have more torque on the counter sprocket or something ? I got the 80 BGF special off ebay.
What am I missing ?
